Y UNITED siualres PATENT OFFICE JULIUs n. sroLL, OF MILWAUKEE, WISCONSIN, As'sIGNOR 'ro PABST CORPORATION, for" MILWAUKEE, WISCONSIN, A CORPORATION or WISCONSIN LABELING MECILANISM Application led January 12, 193.1. Serial 1804508973.`

The invention relates to label aflixing apparatus.

The obje-ct of the invention is to provide a simple and effective apparatus for affixing labels 'to packages or containers that are mounted on an intermittently moving conveyor or carrier. More particularly the invention providesa labeling apparatus includ-l ing a paste applying arm and alabel applying arm soassoeiated that the apparatus may be used .as an attachment for packaging ma- Chines.

The invention further consists in the several features hereinafter setforth and more particularly defined byk claims .atthe Vconclusion hereof. f

In they drawings, 1 is a plan view of theapparatus embodyingfthe invention, parts being broken away; ,Fig. 2 is an lend elevation View ofthe apparatus, parts being brokenaway Fig. 3 is a detail sectional view takenon the broken .line 3-3 of Fig. 2;`

Fig."4 is ardetail side elevation view as viewed inthe directionfof kline 4 4 of Fig. 2; Fig. 5 is a detail side-elevation view as viewed inthe Vdirection of line 5-5of Fig. 2; Fig. 6 is a detail sectionalview takenvon the line 6--6 of Fig. 3. "o Referring to Figs. 1 and 3, the numeral 8 designates an intermittently movable conveyor or carrier here shown as a `rotary 'table mounted to revolve'ona standard 9 and having a Geneva stopwheel 10 associated zthere` with which is engaged by the pin 11 on a crank arm 12 o'fa vertically disposed suitably journalled rotatable vshaft 13 which carries a gear 14 meshing with a gear 15 on a drive shaft 16 adapted to be driven by any suitable source of power. As shown inFig. 1, the tableS has a series of cavities 17 formed therein adapted to carry the package to be labeled past the labeling apparatus embodying the invention.. e

Referring to Fig. 2, the numeral 18 designates a pastearm carrying standard and 19, a label arm' carrying standard and each of these arms are slidably and rotatably mounted y in the framework 20 of the labeling attachment and adapted to swing .and move vertically relative to the table 8. v v The standard 18 carries anarm 21 provided with a head 22 in which paste receiving `pins 23 are loosely mounted and adapted to bel moved into cooperative engagement with aV paste feeding wheel or drum 24 mounted 'on a shaft 25 and adapted to dip into y.a Vsupp-ly trough 2o kcontaining 'the adhesive. Y

The shaft 25 has a sprocket mounted thereon over which a chain 27- runs, said chain also running over another sprocket 28 `mounted on a shaft l29 carrying a bevel gear 30imeshi witha bevel gear 31 on a shaft Y32 which is suitably journalled in thecasing 33 and'car` ries a bevel gear 34 meshing with a bevel'gear 35 on the main drive shaft-16. Y

The standard 19 carries an apr-m36 provided l withza suction finger or head l37 Iadapted to be moved into cooperative relation vwith ia 'stack of labels andthe article upon which the label1 is to be aired. l

The standard 19 has a gear 38-suitablyslidably keyed thereto and meshing with (o. smaller gear 3 8 similarly ykeyedgtozthe stand ard 18 so that when one of said standards Ais turned,v the other will be also through .a different arc of movement. F 0r 'turning these standards in propertimed relation-with the other parts ofthe mechanism,the-standL ard 19`has a crankarm 39 secured to the lower end thereof and having an articulated joint connection through the horizontally disposed pin 40, block 41 pivotedthereon tofs. link 42 vertically pivoted by pins -43 to the block, said ylink at its other end Ahavin .a similar connection through vertically f iS= posed pins A44, block 45,7to `a pin 46.1onthe free end of a lever 47 pivotally mounted at 48 on the casing 33. This lever carries a roller 49 held in engagement Iwith an operaia;k ing `cam 50 by a spring 51, said vcam being mounted on ashaft52 carrying aworm wheel meshing witha worm `541onthe .shaftI` 31; The oscillation of the lever'47 b thecamncts through. the linkage above escribedto-o'scilfi late the standard 19'which ithroughthe gearsA 38 and 38 -Oscillates thestandard 18 vwhich moves through a widerYarc-of travel'than the standard 18, it being noted that because of the articulated connections of the link 42, the standards may also be moved vertically at the same time.

For moving the standard 19 vertically, it

Awill be noted from Fig. 3 that said standard has a colla-r mounted thereon, carrying a pivotbolt 56 that is connected with a lever 57 pivotally mounted at 58 on the'casing 33 and carrying a roller 59 held in en ;agement with a cam 60 on the shaft 52 by a suitable spring 61'; Y Y y Referring to Fig. 4, the standard 18 is moved vertically through the lever '62 pivoted at 63 to the casing 33 and carrying a pivot bolt 64 mounted on a collar 65 on said standard, said lever carrying a roller 66 held in engagement with a cam v67 on the shaft 52 by a spring 68. i i

` The levers 57 and 62 are also adapted to be a'djustably limited in their downward movement by adjustable stop bolts 69 and 70 re spectively.A

The labels are carried in a stack 71, open at one side, and the top orv this stack has one or more projecting ledges 72 of usual construction to resist the tree movement of the topmost label but permit it to be releasedby the proper agency. The labels are ted up wardly by a plunger 73 whose stem or rod 74 is slidably mounted in a frame member ,75

` and at its lower end said rod carries an arm 76 connected by a tension spring 77 with a bracket 7S iXed to the member 75 so thatV whenever permitted to do so, the plunger Vun-A der the action of the spring 77 will act to feed the labels upwardly. Control ofthis feeding action is effected by a clamping means engageable with and releasable from the rod 7 4Y and runder the Acontrol of the lever 57. As shown in Figs. 2 and 5 the rod 74 is mounted i between a iiXed block 79 secured to the mem ber' 75 and a Vmovable block 8O which are normally held in clamping engagement with therod 74 by tension springs 31 connected to opposite sides of said blocks. The movable block 80`is secured to ashatt 82 suitably journalledin bearings 83 on the member 7 5 and carrying a crank arm 84 having a pin and slot connection 85 with a link 36 con niected to thelever 47. Thus during a certain portion of the cycle of movement of the lever`47 the block 8O will be moved out oil engagement with the rod 74 and thus permit the plunger 73 to exert a feeding action on the labels.

For removing the labels from the stack one at a time, the head 37 is connected to a lpipe terminal 87 having a nipple 88 connected by flexible tubing or piping 89 to a suitable vacuum valve 90 Vhaving a nipple 91 for connection' by suitable piping with a suitable vacuum pump not "shown, As the construction of the vacuumV Vvalve forms no partot thepresent invention, it will sui'iice G5 to mention that the-movable elementrot said valve has an operating arm 92 associated' therewith and controlled by a cam 93 mounted on the .shaft 52 and against which said arm Vis held by a. spring 94. The terminal 87 also time the table is moving between its indeX- positions the cam 50 acts on the lever 47 and thence through the link 42 and standardL 18, gears 38 and 38 to swing the standards 18 and 19 and their arms 21 and 36 from the full line positions shown in Fig. 1 to the dotted line positions there shown while said arms 21 and 36 are in an elevated position and then the cams 60 and 67 allow the arms to descend thereby bringing the pins 23 into contact with adhesive on the roll 24 over which said Y pins may swing as they move into and out of contact therewith and' at the same time bringing the head 37 over, the. top of the stack ot labels in the stack 71. The suction valve is then Opened by the cam 93 and with the table 3 at rest the cams 60 and 67 raise the standards 18 and 19 and said standards are then swung under the action of the cam 50, inwardly over the table as shown in full lines in Fig. 1 and then the arms 21 and 36 are lowered to a depositing position with reference to the article to be labeled, then presented in cavities 17 beneath said arms. A As the arm 21 lowers, the pins 23 contact with the article and deposit two spots of adhesive or paste thereon and as the arm 36 lowers, the head 37 brings the label over these spots ot glue, previously deposited on another article. andthe suction is released and as the standard 13 completes its downward stroke the stop 99 strikes the valve stem 98 and opens the compressed air valve and compressed air then flows into the head 37 and blows on the label or applies a blast ot' air thereto with sufiicient force to press the label on' the adhesive coated portion of the article to establish an attached relation therewith. vThereafter the arms 13 and 19 are again moved to elevated position and the cycle of operations isrepeated.
